We toured the offices and factory where [http://www.seeedstudio.com/depot/ Seeed Studio] makes open source hardware in Shenzhen, China. All [http://www.seeedstudio.com/depot/dangerous-prototypes-m-9.html our open source projects] are manufactured and shipped from here.

Visit the major electronics shops in Singapore, and get a guided tour of the Singapore hackerspace. This weekend we were in Singapore for the Maker Faire, so we took a day to do a geek tour. This kicks off the second season of our Global Geek Tours.

Voltage measurements with the Bus Pirate ADC pin are easier than working with a separate multimeter on an analog project. We read a voltage from an MCP4725 I2C digital to analog converter in the demo using the d and D (continuous) voltage measurement commands.

While USB is all around us, the humble (virtual) serial port is still everywhere. Today we explore the serial interface on the Infrared Toy, Bus Pirate, and Logic Sniffer. See a demonstration of the binary interfaces and commands normally used only by software utilities. Grab some terminal software like Tera Term, and Hercules and follow along.

Old ATX computer power supplies are cheap-to-free, and make great lab supplies if you’re willing to add a resistor and short a few wires. Sjaak whipped up an ATX breakout board as an easier way tap and control an ATX supply without any messy hacks.

Flux is a wonderful goo that makes soldering faster and easier. In previous videos we compared different types of commercial flux (Flux off 1, Flux off 2), but did you know it’s possible to make a simple and effective flux at home? We’ll get you started, and don’t miss the giveaway at the end of the video.

Here’s some new and extended project interviews from Bay Area Maker Faire 2012. These took place at the setup, faire, and after party. Generally a few people bring projects to show us, so we interviewed them right at our own table.

Experience the Bay Area Maker Faire from the perspective of a presenter. Veteran Makers talk about their projects, and give advice on preparing for your first Maker Faire. We also take you inside the ‘exclusive’ maker-only pre and post parties. You’ve never seen a Maker Faire video like this.

Today we play around with the latest USB POV Toy hardware and firmware. The POV Toy is a persistence of vision (not division…) device, but we added some special features. First, a USB connection makes it effortless to upload new patterns. Second, an inexpensive accelerometer actively detects the waving motion and syncs the pattern.

This week the flux-off solder flux comparison returns. Our everyday Edsyn FL-22 goes head to head with two AMTECH syringe fluxes in the TQFP arena. Just for fun, we also tried to solder with shards from a solid rosin block. Find out which flux reigns supreme.

The Part Ninja identifies electronic components like transistors and FETs, and measures basic specifications. Get an overview of this new project in this week’s workshop video. If you’re at Bay Area Maker Faire next month please stop by and see it in person.
